BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 542,314, dated July 9,1895.

Application iled July 24, 1894:.

To all whom t may concern.:

Be it known that I, JOHN M. SANDERS, a citizen of the United States,residing at Dalton, in the county of Whitfield and State of Georgia,have invented certain new and useful Improvements in Ealing-Presses; andI do hereby declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to that class of baling-presses known asrebounding-plunger presses, in which the plunger is fed forward tocompress the material in the press-box by a positive movement andwithdrawn or returned to normal position by means of a spring; and theobject ofthe invention is to provide an improved press of thisdescription which shall possess superior advantages with respect toefficiency in operation.

The invention consists in' the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of abaling-press constructed in accordance with my invention. Fig. 2 is adetail plan View of one end of the machine, the rotating casting andsweep being removed. Fig. 3 is a vertical longitudimeral l designates`two parallel' horizontali beams supported at one end by cross-beamsl 2.Upon these horizontal beams, near the outer'ends thereof, is a metalcasting 3, hav- 4ing upon its upper side a boss 4, upon which rests aplate 5, supported at one end by a lshort upright 6.

Journaled in the plate 5 is a rotatable casting 7, comprisingtheinclined arms 8 and radial arms 9. In each end of this casting is apin 10,l on which is journaled an antifriction-roller 12,y for a purposehereinafter ex'- plained. Secured to the upper side of this serial No.518,422. (No man.)

casting are two bars 13, which constitute al sweep, by which the castingis rotated.

Journaled on afpin 14, secured to the casting' and plate 5, at the innerends thereof, is a trip-lever 15, comprising the hub 16, the curved arml7,and the arm 18, rounded at its outer end and formed with an extension19, the inner end of which is beveled, forming an inclined shoulder 20.The curved arm 17 ot' this lever engages between two rollers 2l,journaled in plates 23, secured to the outer end of the plunger 24. Theopposite end of the lever, when the plunger is reciprocated, ashereinafter described, strikes against an elastic buffer 25, secured toa shorstandard 26, which in turn. is secured to one of the horizontalbeams l. l t Secured to the inner ends of'beamsl are two horizontalbeams 27, having superimposed thereon at the opposite ends horizontalboards or beams 28, which form the pressbox. At each end of thepress-box so formed, at top and bottom thereof, are cross-bars 29, towhich are secured vertical bars 30, the top and bottom cross-bars beingconnected together by means of vertical stay-rods 3l. At the rear endthe press-box, at each side, `is formed with a number of slots 32, inwhich are seated a series of detents 34, pivoted on vertical rodspassing through the sides of the press-box. These detents consist ofmetal plates, 'having their inner edges beveled and- Aprovided with'outwardly-extending arms 36,

with coiled springs 43, the other ends of which are -connected with therear top cross-bar of the press-box. The tendency of these springs is topull the plate 40 down into a vertical position.

The numeral designates the bottom of the press-box, which is extendedoutwardly and has secured to it side beams 46 and crossbars 47, which,inY connection with similar crossbars 48, side bars 49, and a top 50,forms IOC a feed-space which receives the bales as they come from thepress-box. The cross-bars at the outer ends of this are connectedtogether by screw-rods 51.

-The numeral 52 designates the plunger-head consisting of a rectangularblock of metal or other material, provided at its upper end with arearwardly-extending plate 53, supported by spring arms 54, secured tosaid head. The front end of this plate projects slightly beyond thishead 52,forming a flange 5G, adapted to strike against the swingingplate 4l on the forward stroke of the plunger. On its outer side theplunger is formed with a lug 57, to which is pivoted plates 58, securedto the inner end of the plunger-rod, forming a knuckle-joint. Secured tothe plunger-rod, intermediate its ends, is a coiled spring 59, the otherend of which is secured to one of the horizontal beams l.

The numeral G0 designates a guide-arm pivoted to the ends of the platessecured to the outer end of the plunger-rod and to a pin 61, secured tothe plate 5 and casting 3, and serves to guide the said rod in itsmovement.

The operation is as follows: The plunger is retracted and the press-boxfilled With the material to be compressed or baled, the detents 34 beingpressed inwardly by their springs so as-to engage with and hold thematerial in the press-box. The plate 40 is also forced into a verticalposition by its springs pressing and holding down any loose materialupon the body thereof. The casting 7 is now rotated by means of thesweep, when one of the rollers on the ends thereof will strike the arm18 of the trip-lever, turning it upon its pivot, and through the mediumof its curved arm forcing the plunger-rod and plunger forward,compressing the materialin the press-box, which is held therein by meansof the detents. When the pressure of the plunger overcomes the tensionof the springs of the detents, the latter will be forced outwardly,releasing the pressed bale and allowing it to be forced into thefeed-space, the flange 56 of the plate 53 also striking the plate 40 andraising up out of engagement with the bale. As the said roller of thecasting passes ont of engagement with the inclined shoulder of thetrip-lever the latter is released, and the plunger and its rod will beretracted by the coiled spring 59, causing them to rebound suddenly. Therounded end of the arm 18 of the trip-lever will strike the elasticbuffer 25, taking up the recoil and preventing. jarring, which would beliable to injure the machine. As the next roller of the casting comesinto Maele engagement with the trip-lever the operation will berepeated.

From the above it will be seen that I provide a very eiiicientbaling-press, which will exert a powerful pressure with the expenditureof but comparatively little force, and in which the plunger is quicklyand automati4 cally retracted after compressing a bale, therebyeffecting a great saving in time and label'. The apparatus is capablefor use in compressing all materials for which the ordinarybaling-presses are employed, and it is very strong, durable, andeconomical in construction.

Having thus fully described my invention, what I claim -is- 1. In abaling press, the combination with the base beams, the casting securedthereto Vnear one end, having a central boss, the plate supported onsaid boss and the rotatable casting having downwardly depending studs onwhich are journaled anti-friction rollers at each end, of the trip leverhaving an extension with which said rollers are adapted to engage andformed with a curved arm, the plunger rod havinga coiled spring, theplates secured to the outer end of said rod, the antifriction rollerlocated between said plates and journaled thereto, forming a guide waywithin which said curved arm plays, and the guide rod pivotallyconnected with the plunger rod and with the casting of the base beams,substantially as described.

2. `In a baling press, the combination with the base beams, the castingsecured thereto near one end, having a central boss and the rotatablecasting having downwardly depending studs on which arejournaledanti-friction rollers, of the triplever, pivoted centrally tothe Stationary casting, having one end curved and the other end formedwith an extension with which said rollers are adapted to engage, theplunger rod having a coiled spring, the plates secured to said rod, theanti-friction rollers located between said plates and journaled thereto,forming a guide Way within which the curved end of the trip lever plays,the guide rod pivotally connected with the plunger rod and casting ofthe base beams, the upright secured to said base beams and the elasticbuffer secured to said upright against which the free end of thetriplever is adapted to impinge, substantially as described.

In testimony whereof I aflix my signature in presence ot' two witnesses.

JOHN M. SANDERS.
